GAS RETORT.

SPECIPICATION f0rming part of Letters Patent 1\T0.310,7&4, dated January 13, 1885. Application filed August 30, 1884. No model.)

in the county of Butte and State of Califor-- nia, have invented a new and useful Improvement in Gas-Retorts, of which the following is a specification, reference being had to the accompanyin g drawings.

My invention has relation to gas-retorts; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a gas-retort embodying my improvemente. Fig. 2 is a sectional detail view on the line a: x in Fig. 1. Fig. 3 is an end elevation. Fig. 4 is a vertical section on the line y y in Fig. 1, and Fig. 5 is a detail view of a portion of the upper retort.

Referring by letter to the accompanying drawings, A designates the upper retort or superheater, and B and G are two lower retorts. z

I have deemed it unnecessary to illustrate the brick-work, as my improvement relates only to the gas-retorts; and the object of the invention is to so arrange the retorts in the brick-work that in the event of a retort giving or wearing out it muy be removed from the brick-work and replaced by a new retort without tearing down the brickwork. This object I accomplish by making the connections for the retorts outside of the brick-work, and also make them removable, as will bc hereinafter further described. The retorts are cylindrical in form and are made of cast metal. They are all of the same size, so that their replacement can be readily effected when necessary.

On the upper retort or superheater,A, at its front end, I provide a mouth-piece, D, which can be taken off in case the retort burns out or breaks, thereby saving the expense of a new mouth-piece. The mouth-piece D is provided with a collar, D, that receives the pipe that leads to the purifying-department.

The retorts A, B, and C are provided with lugs or staples F near their ends to receive the arms of the bars G, which are turned in at their inner ends to form sea-ts for the keys H, and are turned up or formed with shoulders at their Outer ends to form bearings or shoulders f0r the lid-bars G, which are provided with screws G having handles G by which said serews Gr are turned to lock the lids H to place. It will be observed that by unscrewing the hand-screws' the lids may be readily removed when necessary.

The back connection, I, is made of cast metal, the same as the retorts, and is cast in one piece, with an opening, I, in the top, which is closed by a lid, bail,and hand-screw, in order that should the holes or passages from the bottom retorts to the superheater become filled up or clogged with soot or carbon they can be cleaned out by using a straight bar without shutting down work.

The hole or passage J in the superheater is provided With a bail, J, handscrew J and a lid, J that can be swung around while at work for the purpose of cleaning the superheater. The joints at the lids are luted and held tightly to place by the screws when at work. All of the lids are sealed with luting when the gas is being made. By this construction each retort has its entire surface perfectly heated, the trusses L L separating the retorts, and thus presenting the greatest surface to the action of the fire. The heat in the retortsis uniform, and a large surface is presented to the fire. The retorts are independent of each other, and there can be no others, thereby enabling one to have a super heated retort, as described. The connections being outside of the brick-work, it requires less time to clean the retorts than heretofore. On the front of the two bottom retorts there are two filling-pipes, O, and when oil is used it enters the retorts through these pipes.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination, with the retorts A B C, separated by trusses and provided with staples near their ends, of the lids, the head bars turned in at their inner ends and turned up at their outer ends, the keys H, the lidbars Gr, and the hand-screws, substantially as Specified. A

2. The combination of the retorts B and C and the superheater-A, connected by re- 5 movab1e end connections, said superheater being provided with the removable mouthpiece D, substantially as specified.

3. The combination, with the retorts A B C, separated by trusscs and provided with 10 1ugs near their ends, of the removab]e end connections and the femovabie mouth-piece, substantial1y as specified.

In testimony that I claim the foregoing as my own I have hereto aflixed my signaturein presence of two witnesses.

APPIOUS CL AUDIOUS SWAIN.
